The basic concepts and methods on performance and effectiveness evaluations at the feature-level fusion model of multi-biometric cryptosystem are concentrated on in this paper. Single biometric cryptosystems were developed to obtain win-win scenarios for security and privacy. They are seriously threatened by spoof attacks, in which a forged biometric copy or artificially recreated biometric data of a legitimate user may be used to spoof a system. By using cryptographic theory, firstly, the formal definitions related to multi-biometric cryptosystems are formulated.
